Glass houses / Anne Stuart.

"What was it they said about throwing stones? All that stood between Michael Dubrovnik and the creation of Dubrovnik Plaza was a building that begged for demolition, and Glass House's obstinate owner. Michael had met his share of Park Avenue blue bloods, but Laura de Kelsey Winston was a first in his experience. Laura had fire. She had spirit. She also had the colossal gall to challenge the most powerful and feared man in Manhattan. Michael thrived on challenges and welcomed a battle of wills. And this was one battle he was going to love.
